Sano, 20, will have Tommy John surgery to repair a partially torn ulnar collateral ligament, Berardino reported. That surgery generally carries a six-to-nine month recovery process, although Twins assistant general manager Rob Antony told Berardino that Sano should be back swinging a bat in four months.

The report on Sano—who is the cover boy for BA’s 2014 Prospect Handbook—starts with the power, which earned him best power prospect honors in both the Florida State and Eastern leagues.

Sano also worked with roving infield instructor Paul Molitor to improve his footwork and hands at third base, but they still need polishing. He has a plus arm and made progress in 2013, committing 23 errors and nearly halving his total in 2012. He’s a below-average runner.

Sano signed out of the Dominican in 2009 for $3.15 million and quickly rose to the top of the Twins’ prospect rankings before ceding that spot in 2013 to Buxton. He was expected to begin 2014 at Triple-A and make his major league debut sometime during the season.
